A 3.73 x 10 kg subway train is brought to a stop from a speed of 21.5 miles/hour in 3.73 m by a large spring bumper at the end of its track. What is the force constant k of the spring? Note: to write large numbers in scientific notation, the syntax is to replace 10^ with e, so 4x100 is written as 4e6.
